Super Anchor 8501 G-Clamp Fall Protection System – Non-Penetrating Reusable Anchor
The Super Anchor 8501 G-Clamp Fall Protection System is a temporary, reusable, and non-invasive fall arrest solution that works on virtually any roof type. This innovative system eliminates the need for penetrating fasteners by using friction and tension to create a robust, OSHA-compliant anchor point. By securing under the eaves and over the ridge, the G-Clamp system is ideal for contractors and homeowners who require reliable fall protection without damaging the roofing material. For projects requiring a permanent, truss-mounted solution, explore the Super Anchor 2830 ARS 2x4 Anchor.

Zero-Penetration Safety: Absolute Genius Engineering
The G-Clamp System installs in 10 to 15 minutes without the need for power tools, screws, or nails. The system utilizes specialized G-Clamps positioned under the eave (minimum 2" overhang required), a Saddle or Hinged Peak Anchor at the ridge, and heavy-duty ratchet straps to create a stable "wrap-around" anchorage. On pitched roofs, this creates a Grappling Effect where the twisting and gripping motion of the clamps adhere to the roof structure under applied force. This zero-penetration design means no holes to patch and no risk of water leaks, making it the premier choice for 2026 work on asphalt shingles, standing seam metal, wood shakes, clay tile, and slate roofing surfaces.
In the video above, we demonstrate the high-performance features of the G-Clamp system. Watch how it creates a structural, tension-based anchor point on most roof types without a single penetration. Click to see the absolute genius of G-Clamp safety in action.

Industry Success Stories: Contractor Testimonials
"As the Safety Director for a painting contractor, I am very pleased with the Grappling Clamp Set. It has allowed our painters to safely do their job without installing multiple D-rings into our customers' building."
— Bill Poss, Sabelhaus West
"I have used them on three separate job sites and found them very easy and fast to set up. I actually feel safer using this system than the tie-offs that are on most of the newer roofs."
— James Jorgenson, J&J Repair and Renovations
"With over 30 years in the painting and contracting business, I have come across many methods of tying off. This invention puts safety in the contractor's hands. It is innovative and a great asset to any job site."
— Richard Larsen, Professional Painter/Contractor
"In fact, without access to these units I would have had to pass up several jobs because they were far too unsafe. Every paint company, homeowner, and specialty contractor should own at least one."
— Nicholas T. Spence, Professional Union Painter
"Many cleaning contractors wouldn't clean our steep roof because we didn't have attachment points. G-Corp was able to clean our roof cost effectively because of their unique rigging system."
— Craig and Mary Ann Donald, Homeowners
Technical Specifications & Operational Safety
The Super Anchor G-Clamp system is engineered for 2026 industrial safety standards, requiring a structure capable of withstanding a 5,000 lb load. To ensure maximum effectiveness on standing seam or ceramic tile roofs, riser blocks with friction pads must be used to prevent crushing and maintain a stable grip. The pitch adjustment arm must remain vertical to function properly, and users should never work more than 45° to either side of the anchor to minimize swing-fall hazards.
- System Type: Non-Invasive Temporary Fall Arrest
- User Capacity: 1 User in Fall Arrest | 2 Users in Fall Restraint
- Max Free Fall: 6 Feet (Requires shock-absorbing lanyard or retractable lifeline)
- Structure Compatibility: Wood, Steel, or Concrete with minimum 2" eave overhang
- Compliance: OSHA 1926.502 and U.S. Patent 9,248,323

Super Anchor 8501 G-Clamp System FAQ
1. Does this anchor system require an overhang?
Yes. The G-Clamps must be secured to an eave or fascia overhang of at least 2 inches. On roofs with enclosed soffits, the T-bar should be centered on the rafters using nail holes as a guide. The system relies on the structural integrity of the eaves and opposing tension to provide a safe tie-off point.
2. Is it safe to use on fragile tile or slate roofs?
The G-Clamp system is specifically designed for these surfaces because it does not require drilling. For tile or standing seam metal, riser blocks and friction pads are required to prevent damage. If you require a permanent solution that remains hidden under tile, consider the Super Anchor 2815-T Tile Anchor.
3. Can I use this for more than one worker?
Yes, this system allows for 2 workers when used in Fall Restraint (preventing you from reaching the edge). If being used for Personal Fall Arrest (stopping a fall), it is limited to 1 user with a maximum free-fall of 6 feet.
4. How tight should the ratchet straps be?
The ratchets should be tightened simultaneously until there is no movement in either the G-Clamps or the ridge anchor. Over-tightening can damage the roof, so tension should be constant but balanced. Always ensure the strap logo is visible on the top side and there are no twists in the webbing.
5. Does this work on flat roofs?
Yes, it can be used on flat roofs with overhanging parapet walls. The system "Clamps" around the edges and utilizes extensions to raise the center anchor, creating a functional tie-off point. For traditional structural post solutions, see the Super Anchor 1042-W Anchor Post.
6. How do I avoid common mistakes during installation?
- 1. Alignment: All three pieces (two G-Clamps and one anchor) must be connected in a straight line over the peak of the roof.
- 2. Pin Safety: Ensure all wire-locking pins are locked on the inside of the system to prevent accidental disconnection.
- 3. Structural Condition: Never use this system on a roof with rotten or deteriorating supports. Verify structural integrity before every shift.
